Answer:
She can buy 0.8 cents worth of Gummy worms and 1.2 cents worth of sour patches
Step-by-step explanation:
Keisha is allowed to buy only 2 pounds bag of candy.
Now, she can choose either gummy worms or sour patches.
Gummy worms are 0.4 cents per pound while sour patches are 0.6 cents per pound.
Thus, maximum amount she can spend on gummy worms is; 0.4 × 2 = 0.8 cents
Maximum she can spend on sour patches is; 0.6 × 2 = 1.2 cents
She can buy 0.8 cents worth of Gummy worms and 1.2 cents worth of sour patches
